A flawed past is the worst excuse against striving for a better future.
Compared to say Japan.
EDIT: not sure why the downvotes. Japan's whitewashing of war atrocities (eg Nanjing [1][2]). Is this Japanophilia? Or just that I'm not denouncing the current German education system?
Any inhabitant of the temples will explain how german visitors would (infrequently) vandalize the temples. Not the intentional decoration (which is obvious) but the crude carvings into random wooden walls. I'm a little surprised that you can no longer find images of these carving after a few minutes of searching on the web. That's unfortunate, but I stand by my observations.
